[Development and innovation of arthroscopic techniques].

In this special issue, several papers related to clinical application of arthroscopic surgery are published, which present the current situation of arthroscopic techniques in our country. As a technique of minimally invasive orthopedics, arthroscopy is used in examination, diagnosis and treatment of joint diseases, which is the trend of modern surgery. Arthroscopy has been widely used in surgical procedures in knee diseases, and now it expands the scope of application to other joints, such as shoulder, elbow, wrist, hip, ankle and even smaller joints. The application scope of arthroscopy has spread from arthroscopic debridement to reparative and reconstructive surgery. Some innovation has been made in extra-articular surgeries. Researchers conduct in depth study and exploration in the basic and clinical application of arthroscopy. Arthroscopic surgery has become an indispensable branch of modern orthopedics.
